Hope this will make people using feed_command less likely: this hides bugs. Already found at least two: 1. msgpackparse() will show internal error: hash_add() in case of duplicate keys, though it will still work correctly. Currently silenced. 2. ttimeoutlen was spelled incorrectly, resulting in option not being set when expected. Test was still functioning somehow though. Currently fixed.
